TNT "OFFICE y This invention:relatesl to 'window cnstructiom and aimsto; provideln'ovel means wherebyV awin- Y dow may be supportedin awindow `jamb arranged for standard sash, the construction of the windowbeing such that it will compensate for inward pressure, ldirected.there'against which would otherwise cause the window to becomemisplaced.

An important object of the invention 1s to provide a sh'oer whichmay-bevpositioned over the usual vwindow guides of aH-window framemtheshoes having grooves to receive curved plastic windows..

f With the foregoing and other objects, 1n view which will appear as thedescription proceeds,'the .invention consists of certainA novel details'ci con- .struction and combinations o'f parts, hereinafter more fully'described and pointed out 1n the claims, it being understood-thatvchanges may be made -in the construction and arrangement ofA parts`without departinglfro'rn the spirit ofthe invention as claimed.

Referring to the drawings: l

Figure 1 is an elevational view lllustrating windows constructed inaccordance with the 1nvention, as mounted within a window frame.

Fig. 2` is a longitudinal sectional View throughv the windows.

Fig. 3 is a transverse sectional view through the windows lookingtowards the upper part of the frame.

Fig. 4 is a transverse sectional view through a modied form of theinvention, taken on line p 4 4 of Fig. 5.

Fig. 5 is a sectional view taken on line 5-5 of Fig. 4. Y n u y Fig. 6is a fragmental sectional View lllustrating a further modified form ofthe invention.

Referring to the drawings in detail, the reference character 5 indicatesa window framein which the 'guide members 6 are secured, the gu1demembers 6 being providedrwith curved outer and inner surfaces providinga plurality of longitudinal grooves. y

The reference character 1 indicates the upper pane of the outer window,while the reference character 8 indicates the lower pane of the outerwindow. The reference character 9 indicates the lower pane of the innerwindow, while the reference character l0 indicates the upper pane of theinner window. These windows are arranged in spaced relation with respectto each other, providing an air space therebetween.

At the ends of the panes are curved shoes Il that are curved to conformto the curvatures of the guide members 6 so that they may slide freelyw-harles J .,Roos, Muskegon, Mich. tappiiqatiopntgust ,2, 194s, serialNo. 41,960 faclfma (c1. 16a-,114)

`2 within the guide members. It will of course be understood that it'iscontemplated to construct the panes il, 8, 9 andvlbf plastic materialVof a Iiexible character Vso that thepanes may be bulged in a manner as'shown by Fig. `3 of the drawings so that when pressure 'is directedthereto, the

curvatures ofthe panes will besuch as to compensate v*for this pressureto `eliminatc'e'any* possibilityffof the panes being blown-from thefguide members In the form of the invention as shownby Fig. /lof thedrawings, the structure is designed for use inconnection with the usualwindow sash frames and in this 'form offthe invention, the referencecharacter l2 indicates the usual sash guides that include spaced ribs|3.between which the `usua-lfwinclow sashesoperate. When supportingapplicants deviceginjthe usual window sash guides, shoes .-Mfareprovided, whichshoes are formedV with grooves 'disposed in the outersurfaces thereof, the grooves'accommodating the spaced ribs I3 of thevsash guides, securing the shoes against movement. The inner surfaces ofthe shoes are formed with spaced grooves l5 that accommodate the sideedges of the panes IS constructed of flexible plastic material, so thatwhen positioning the panes I6, they may be bulged as clearly shown byFig. 4 of the drawings to insure the panes being securely held withinthe grooves, and at the same time permit the panes I6 to slidelongitudinally of the grooves, when pressure is directed to the panes Iin an eort to elevate or lower said panes I6.

While this structure insures the mounting of the window panes within theshoes, it also compensates for any outward pressure which may bedirected against the panes to prevent the pressure from dislodging thewindow panes.

The upper pane of each window is formed with an inwardly extended flangeI'l which is curved to conform to the curvature of the window pane, theanges contacting with the adjacent window panes to close the spacebetween adjacent window 'panes as clearly shown by Fig. 5 of thedrawings.

A further modied form of the invention is illustrated by Fig. 6 of thedrawings-in which the guide member I8 is secured within the window frameIS, the guide member being formed with a curved surface to t within thecurved outer surface of the shoe 20, the shoe 20 and guide member I8being formed with aligning openings for the reception of the screws 2|whereby the guide member and shoe 2G will be secured in position.

As shown, the shoe is formed with a longitudinal groove in the innersurface thereof, the groove having laterally extended portions 22 thataccomodate the longitudinal enlargements 23 of the windows 24 wherebythe windows may be readily moved vertically. It will of course beunderstood that these shoes 20 are formed at opposite sides of thewindow frame to support the opposite edges of the window panes which areheld therein.

From the foregoing it will be seen that due to the constructions shownand described, I have provided means for supporting plastic window paneswithin window frames so that the window panes will be bulged in adirection to compensate for pressure directed thereto to prevent .the

window panes from being displaced -by pressure v caused by an explosion.

Having thus described the invention, what is `the window panes movablyheld in said spaced grooves of the shoes, whereby said shoes are forcedlaterally into contact with the sash guides.

2. In a plastic window construction, a window frame, guide memberssecured within the window frame, said guide members havinglongitudinally disposed ribs Aspaced apart defining window grooves,window shoes having spacedgrooves in the outer surfaces thereof andgrooves in their inner surfaces, the ribs of the guide members beingfitted in the grooves of the shoes, supporting the shoes Within theguide members, pairs of outer and inner plastic window panes fitted forsliding movement within the grooves of the shoes at the inner sides oisaid shoes, and said plastic window panes being outwardly bulged andtending to flatten out for holding said window panes within theirgrooves by frictional contact therewith.

3. In a plastic window" construction, a window frame, guide memberssecuredwithin the frame, said guide members having spaced longitudinalribs and grooves, shoes having spaced grooves in their outer surfacesfor receiving the ribs of the guide members, said shoes having windowpane receiving grooves in. their inner surfaces, outwardly bulgedplastic window panes tending to Hattenl out, enlargements carried bysaid window panes and extending longitudinally along opposite side edgesthereof, said enlargements entering the window pane receiving groovesinthe shoes for slidably mounting the vwindow panes within theshoes.
